Abstract excerpt

Subunit 6 of the mitochondrial cytochrome bc1 complex regulates the activity of the bc1 complex in Saccharomyces cerevisiae but is not essential for respiration. To test whether QCR6, the nuclear gene which encodes subunit 6, might be functionally redundant with any other gene(s), we screened for...
